I'd start with the typical getting a restraining order. then you also will likely have to move, preferably to a different city or state if you can, if you can't then just move to the opposite end of your town or city. change your phone number, delete your facebook, twitter, dating sites, change your email, don't tell any of your friends your number, that's important, block your number when you call your friends or family. Don't show anyone where you live. Don't put your new address on your Drivers license or any other item coming to your new address. Rent a mail box and use that for anything requiring an address, or get your mail sent to a trustworthy friend or relative for a time or to your mail box rental. Don't pick up any phone call that you don't recognize the number. Don't record a voice message on your phone or even don't record "name" when it asks you to. Just have it use the standard built in computerized voice greeting. Screen your calls that way by only returning calls of people that you don't recognize the number. Stop gossiping or dramafesting with friends as your bound to let something slip. Next thing you know he'll find out threw the "grape vine" that way. There's a lot of books written on this subject. Amazon stuff like "how to disappear". You'll learn all about how to hide your identity so he can't stock you anymore. Don't threaten him, or talk to him, or negotiate with him or any of his friends or his family. Just disappear for a while. Like maybe at very least a year, 3 years is better. Then after a while you likely don't have to be as guarded anymore. You could likely get back to normality. It's sad that you have to deal with such harsh adult realities when your still so young. But what doesn't kill you makes you stronger thats a guarantee. But don't judge all guys based on this one idiot. Most others are normal right. Try and get some counselling to . Good luck okay.
